' To whom it may concern.'

Be it known that I, EDWARD F. DUNNE,

Jr., a citizen ofthe United Statesyand a resident of' Morristown, countyof Morris, andI State of ew Jersey, havel invented new and useful Improvements" in Machines for vUse in Makin Boxes, of whichl the following is a speci cation.

This invention relates to machines for use in making boxes, crates, box or crate blanks `or parts thereof, and more particularly to machines for use in making wire bound boxes, crates, -box or crate blanks and the like.

Among other objects, the inventionV is intended to provide a machine of the class described in which fastener-setting mechanism operates upon continuously moving work and to provide such a machine'with mechanism foigcontrollably positioning the fasteners inthe work.

The inventionwill be best understood by reference to one illustrative embodiment' thereof shown|n1 the accompanylng draw-I ings in which :v

Fig. 9 is a side elevation of the same.' The present invention 1s directed to 1mprovements in the' type of machine disclosed in the application of Osceola-C. Thompson,

serial No. 375,195, filed April 2o, 1920, which consists generally of a gang of fastener-setting mechanisms operable to apply binding wire to box pa ts presented thereto in properly assembled relation by work-forwarding means, the work being fed continuously beneath the fastener-setting mechanisms which operate at intervals to drive fasteners into the moving work, and ,mechanism for automatically Severin Athe vbinding wire between successive wor as- `semblies. The improvementsconsist in providing such a machine with mechanism for controllably positioning fasteners at selected points in the work.

In the Iillustrative machine, the workforwarding means comprises the endless conveyer chains l appropriately formed to re'- ceive cleats c and sheetsof side material .s

for box orcrate blanks and spacer blocks 2,

adjustably secured to flanges?) of thechains -1 for spacing the cleats @and sheets s of adjacent sections of la blank and for spacing successive blanks.l Conveyer chains 1 run `in channel guides 4 `and pass over driven sprocket wheels 5 on shaft 6 at thedelivery end ofthe machine and over idler sprocket Wheels 7 on shaft 8 at the receiving end of `the machine, said shafts and 8 being journalledlin suitable bearings inthe frames 9 at either side of the machine, which framesare rigidly connected and supported by cross frame members 10. The chains 1 comprising'` individual links may be vadjustable.

laterally to accommodate different sized boxes and the shaft 8 may be adjustable toward and from shaft 6 to'` accommodate vthe removal or insertion of individual chain links to shorten or lengthen the cony .veyer chains 1.

` sides.,

The binding Wires 12 which are carried by suitable supply reels 13 and pass over rollers 14 are fed under rollers 15 at the feet of the stapler bodies and are pulled. along by reason of .their atachment to the work at preceding points.

. 'Ihe conveyerchains 1 are advanced continuously through a feed mechanism comprising sprocket Wheel 16 keyed to a main shaft 17, sprocket chain 18, sprocket Wheel 19 carried by a sleeve 2O on stud 21 suitably fastened to the frame of the machine, and spur gears 22, 23, 24, 25, 26 and 27 spur gear 27 being-revolubly mounted on sprocket shaft 6 and having secured to its inner rim a series of pawls `28 adapted to'engage a' ratchet 29 keyed to shaft 6. This arrangementl lpermits the shaft 6 and `conveyer chains 1 to be moved faster, at intervals, than gear 27, forfthe purpose hereinafter explained. In the illustrative machine, the reduction gears are preferably proportioned andarranged to movethe conveyerl chains l approximately two inches per revolution of the main shaft, but it Will be understood that the feed mechanism may be proportioned and arranged to produce a longer or shorter movement of the conveyer chains per revolution of the main shaft Without departing from the invention. j

In the illustrative machine the Staplers 11 are carried bya carriage 30 which is reciprocable longitudinally of the vvork in guides 31 of the main frames 9. The individual Staplers 11 which are adapted to form and drive a staple upon each revolution of the main shaft 17 may be of any suitable type, for instance, of the typedisclosed in said application of Usceola C. Thompson above/referred to,and are mountedon a crosshead 32 set in the side frames of the carriage 30 and are operated by the vertically reclproeating Across head 33 slidably mounted in guides 34 of the side frames of the carriage 30, all as illustrated and described in said application above referred to.

Cross head33 is reciprocated verticallyY through piotman 35 and eccentric 36 on the main shaft, therebeing 'similar operating mechanisms at either side of the machine.

Staple wire 37 from which the staples are formed is fed to the Staplers 11 from suit-v able supply reels 38 over rollers 39 and betip/veen palrs of feed rollers (not shown), carried by shafts (not shown) journalled in the side frames of the carriage 30,-said feed rollers being operated by aratchet and pawl ymechanism 4() through pitman 4l and eccentric 42 of the main shaft, all as illustrated and described in said application of @eccola C. rlhompson above referred to.

The stapler carriage 30 is moved with the Work during a stapling operation by means of a cam 43 on the main shaft 17 operating on a. roller 44 carried at one end of a bell crank lever 45 pivoted at 46 to the frame of the machine the other end of which .is pivotally secured to a bracket 47 carried by the carriage 30 so that when the roller 44 is raised by the cam 43, the carriage 3() will be advanced with the Work.

meneer lThe cam 43 and the lever 45 are so formed, adjusted and correlated with respect to the operation of the Staplers -11 and the Workfeeding mechanism that the carriage 30 is preferably advanced synchronously With the work during the lower half of the cycle of operation of the staplers during which time staples are driven into the Work and is free to return to initial position through a spring 48 during the upper half of the cycle of operation of the Staplers. Thus in the illustrative machine in which the Work-forwarding chains 1 are advanced approximately two inches per revolution of the main shaft 17 the Staplers will move with the work approximately one inch and then return one inch to initial position thus producing a normal space of two inches between staples.

In the machine of the Thompson application above referred to, staples are driven into the moving work at regularintervals. ln applicants machine provision is made to vary the distance between staples and controllably position staples at selected points in the work. This 1s particularly advantageous in that staples may be kept out of joints between the box sections and may be positioned in such a manner as to obtain a maximum strength with a minimum number of staples.

For varying the distances between staples and controllably positioning them at selected points in the work, mechanism is provided to -controllably vary the movement of the conveyer chains l during the return or inoperative movement of the stapler carriage 30,

thus presenting a different point on the work tothe Staplers for the next operation than that which would be presented normally in the operation of the machine.

As shown in Figs. l, 2 and 3, said mechanism comprises a reciprocating pawl 49 adapted yat intervals to engage and advance staple positioning blocks or lugs 5,0 adjustably secured in any suitable manner to a flange 51 on oney of the chains l opposite selected fastener-receiving points on the work. Pawl 49 which rests on the flange 51 is reciprocated longitudinally of the chain and in the path of blocks through a bell crank lever 52 connected to an eccentric 53 by a link 54. The construction and arrangement of the blocks 50 and pawl 49 is such that on the inoperative movement of the pawl to the right in Fig. l, it passes over the stapl o positioning, lugs 5() and onr its operativd stroke to the left in Fig. l, it engages and pulls any such lug which may be in its path of travel. This construction and arrangement is best shown in Figs. 8 and 9. As there shown the blocks 50 are provided with bevelled surfaces and the nose of the pawl is also appropriately bevelled at 61 so that when the pawl 49 encounters a block 50 on its inoperative movement to the right it rides llU up over the block and snaps into operative position behind said block through the action of a spring 62 attached at one end to the pawl 49 and at the other end to leverv 52. Blocks 50 may be secured to both chains 1 and a pawl 49 'may be provided at either side of the machine. 4

Thethrow of the pawl 49 and the reciprocations of. the stapler carriage 30 are so arranged that the pawl and the staplers i move from and toward each other andlmeet at the time' the stapler carriage starts its movement with the work. In other words, viewing Fig. 1, when the pawl 49 moves to the right the Staplers' moveto the left thus increasing lthe distance between them and vwhen the pawl 49 moves to the left thestachains are moving one inch to the. left so that the pawl 49, in effect, has -a four inch throw relative to the lugs 50 fon-the continuously moving chains 1 and when the pawl 49 is moving with the chains 1 on its drive stroke the paw] travels three inches while the chains are travelling one inch. Thus if the pawl 49 in its movement with the chains l encounters a lug 50 in its path, it will engage the lug and advance the chain at an increased speed and bring the point on the work opposite theengaged lug beneath the Staplers at the `time the stapler's start their movement forward with the work. As pointed out hereinabove, the pawl and ratchet connection between gear 27 and a sprocket shaft 6 permits this independent movement of the conveyer chains. The pawls 28 during such movement click idly over the teeth of the ratchet 29. A

ln oper tion the operator sets the spacer blocks 2 oh flanges 3 of chains 1 in proper relationship to receive the cleats o and sheets s for the box b1anks.- vHe then'de termines by eye or otherwise the points relative tol ledges of the sections of the blanks at which he desires staples to be driven and places staple positioning lugs or blocks 50 on flanges 51 at the selected points. lf he desiresl to position intermediate fastenersin the bodies ofthe sectionsadditional lugs 50 may be secured to the flanges 51 at the selected .fastener-receiving points ln some instances the fas teners ,intermediate the first and last fastener of 'each section are spaced normal distances apart in which event the additional lugs 50 may be dispensed with. When the machine is started fasteners will be i driven every two inches apart except when the pawl 49 propulsively engages a lug 50, in which event, the chains 1 will be advanced more rapidly and the point opposite the en aged lug will be presented beneath'the riving point of the staplers in position to move therewith during the next fastener-driving operation. iIt may happen in the operation of the machine that the normal feed ofthe work will bringa selected fastener-receiving point on the which event the paw] 49 will not affect the 'feed of the work, for instance, if' the point selected for a fastener happens to be 'just two inches behind the last fastener driven the normal feed of the work will advance said point to the Staplers and pawl 49 will not perform any operation. If, on the other hand, the selected. fastener-receiving oint is'more Ithan two inches behind the ast-fastener driven, for

instance, three inches behind the last faswork ,to fastener-receiving position, in

tener driven, the pawl, 49 will engage the block 50 opposite said selected point and advance the work an additional inch overthe normal feed. Thus it will be seen that in the illustrative machine the feed of the work during any one cycle of operation of f the machine may be controlled to cause a feed movement of` any distance 'between two and four inches, thus enabling the positioning of fasteners anywhere from two to four inches apart. It will be understood that the gures given are only illustrative and maybev invention; v y, l

Thus it wlll beseen that mechanism is provided to controllably position the driv ing of fasteners into continuously moving work and that Athis result is-'accomplished by varying the extent ofi-movement of the continuously moving work during intervals i between fastener-driving operationsu For clinching the staples von the under side of the work the movable carriage 30 aried without departing from the is provided with a cross bar 55, secured to the side frames of the carria e and exi irectly `bef tending between said frames heath the Staplers 11 to which bar `clincher' blocks or anvils 5 6 may be adjustably se cured directly beneath each stapler and upon which the staples may be driven and clinched.

- j For removing the completed blanks from the work-forwarding means, the machinei Cn or stripper bars the Wires connecting one blank with another may be severed by an automatic cutting mechanism 58.` Said Cutthe cutting mechanism operates automatically vto sever .the Wires between box blanks after a completed blank has passed the stapling plane.

Power for operating the machine may be applied in any suitable manner, for instance, by po'Wer pulley A59 shovvn in Fig. 3 which may be controllably clutched to the shaft 17 by any suitable clutch mechamsm.

lt Will be understood that the expressions continuous, continuously and the like, as used in the specification and claims in connection with the movement, progression or feed of thevvork or 'Work-forwarding means is intended to distinguish from an intermittent or step-by-step movement, progression or feed and is intended to include any uninterrupted movement; progression or feed ofthe Work or Work-forwarding means during which the Staplers operate upon the moving work.

Obviously, the present invention is not limited to the particular embodiment shown and described but may bev variously embodied and the particular construction shown may be variously modified, as will appear to those skilled in the art.' Furthermore, it is not indispensable that all the features of the invention be used conjointly since they mayl be used to advantage in various combinations and vsub-combinations.
